Cal-Nev-Ari, NV
Cal-Nev-Ari wildfire risk explained
USFS scores Cal-Nev-Ari at the 82nd national percentile for wildfire risk to structures (in USFS's highest wildfire-risk band nationally), a figure built from 216 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Cal-Nev-Ari at the 84th percentile, close to its 82nd-percentile risk score.
What "at risk" means for the buildings here
Most of Cal-Nev-Ari's buildings (54.2%) sit in the Indirect zone, where wind-blown embers rather than flame front are the mechanism USFS is scoring — ember-resistant vents and non-combustible roofing are the interventions this pattern favors, more than defensible space alone.
Cal-Nev-Ari against the rest of the country
Cal-Nev-Ari's 82nd national percentile looks worse in isolation than its 34th ranking inside Nevada does — this place is on the milder end for its own state, by 48 points. Among the 31,521 US communities USFS scores, Cal-Nev-Ari ranks 5,581 for wildfire risk (1 is highest) and 24,276 by building count (1 is largest). Within Nevada alone, it ranks 81 of 123 places by risk. See the full county-by-county picture for Nevada on its state page.
Cal-Nev-Ari and the insurance market
Cal-Nev-Ari's 82nd-percentile, very high rating is the kind of score behind a broader national pattern: insurers pulling back from the highest wildfire-risk markets, non-renewing or declining new policies outright, most visibly in California. Shopping around, not assuming automatic renewal, tends to matter here.
Lowering exposure, not just insuring around it
Cal-Nev-Ari's 54.2% Indirect-exposure share points at embers, not flame contact, as the main pathway — ember-resistant vents and non-combustible roofing rank ahead of defensible space here. Detail in the home-hardening guide.
Where Cal-Nev-Ari's figures come from
Cal-Nev-Ari's 82nd-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. The exposure-zones guide covers what Cal-Nev-Ari's dominant indirect exposure actually means, with real examples from across the dataset.
